Do you find the Portal useful? We’re asking you to please take a minute today to keep our work going.
This year we added 1.2 million pages of material to the Portal and we need your investment to continue growing.
We’re only $100,000 away from meeting our year-end goals for the Challenge Grant we received from the National Endowment for the Humanities.
During our spring appeal, the average donor gave $30, but if even half the people who use the Portal this month give $5,
we’d meet our entire goal to raise matching funds for the endowment immediately.
The Portal connects people to the past, and your support will ensure its future.

her research has obviously been extensive, and the book reads easilyenough. Only one criticism can justly be raised and that is the fulsomepraise lavished without exception on all the port commissioners, portdirectors, bankers, and civic leaders who played a role in the port'sgrowth. Perhaps a more critical appraisal would have better servedthe author here. Also, the hazards of pollution and industrial wastein the channel area are dismissed with a single, slighting paragraph.Such an approach may be unavoidable in a work of this type, but itunfortunately mars an otherwise well-written book.University of Houston STANLEY E.

They rep-resent the beginnings of a report on one of the most exciting archaeo-logic discoveries made in the New World; but the discovery was notmade suddenly or by accident. The work by Richard S. MacNeish andothers had indicated by 1950 that maize (corn) probably was firstdomesticated in Middle America and possibly more than 5,000 yearsago. Further field work eliminated much of Middle America andpointed to the region between Chiapas and the Valley of Mexico asmost likely to provide data on the beginnings of agriculture in theAmericas. A combination of logic and luck led to the selection of theTehuacan Valley in the Mexican states of Puebla and Oaxaca as thearea to be intensively studied by an interdisciplinary team of expertswithin the framework of the Tehuacan Archaeological-Botanical Proj-ect. This project was initiated and headed by MacNeish, sponsoredby the Robert S. Peabody Foundation, and underwritten by theNational Science Foundation.The aims of the project were immediately to establish an "uninter-
